I recently completed the nose gear SB on my 7A and it all went very well. Everything fitted including my NG fairing.
I thought it was not the answer to the problem but did it for insurance and re-sale reasons and because I don't actually know that it won't help.
I noticed a few changes.
With the old fork, I usually got a momentary resonance, kind of like a shaking, after take off while around 90 kts and climbing and accelerating. I don't get it any more.
The new set up seems a little stiffer to me and just feels a little stronger. I've only flown from pavement so this is not a real test, just an impression.
These two things got me thinking that shortening the lower, vertical portion of the NG leg means that less bending moment can be applied by rearward pressure on the wheel. In effect, if true, that makes the long, diagonal part less prone to flex under pressure. I know it flexes upward because of the rubbing on the leg fairing from the intersection fairing, but I am talking about possibly having less bending down, trying to follow the fork under aft-pointing loads.
I'm no engineer - not even close. What to those of you who are engineers think about that?
